FRAMING-TOOL.

Specification of Letters Patent.

Application filed March 23, 1911.

Patented Dec. 26, 1911.

Serial No. 616,466.

To all whom it may concern:

Be it known that I, HENRY IZARD, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Framing-Tools; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in framing tools.

One object of the invention is to provide a framing tool having animproved construction and arrangement of parts by means of which thetool may be employed as a bevel, try square, miter square, protractorand stair gage, and by the use of which rafters may be readily framed atany desired pitch and the points for plumb cuts, heel cuts or back cutsmay be readily indicated.

Another object is to provide a tool of this character which will bestrong, durable and inexpensive in construction, efiicient and reliablein operation and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrange ment of parts aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings: Figure 1 is a plan view of my improvedtool showing the parts arranged in position for use; Fig. 2 is a similarview showing the parts folded; Fig. 3 is a rear edge view with the partsin the position shown in Fig. 2; Fig. 4 is a cross sectional view on theline 44 of Fig. 2; Fig. 5 is a similar view on the line 55 of Fig. 2;Fig. 6 is a detail perspective View of the protractor plate.

In the embodiment of the invention I provide a base member 1 which formsa straight edge and has arranged therein a longitudinal disposed slot 2.The slot 2 near one end of the base 1 is enlarged and has pivotallymounted therein a substantially semi-circular protractor plate 3. Theplate 3 is revolubly mounted on a combined pivot bolt and clamping screw4 which is arranged through the opposite yieldable sides of the basemember 1. On one end of the bolt 4 is fixedly mounted a short operatinglever 5, while on the opposite threaded end of the bolt is arranged aclamping nut 6, said nut being countersunk in a recess 7 formed in thelower side of the base member 1 as shown. By providing the clampingscrew 4 the sides of the base member 1 may be compressed together intotight clamping engagement with the plate 3 thereby holding the latter inits adjusted positions.

On the square edge of the protractor plate 3 is arranged a centrallydisposed extension 8 through which is formed a longitudinal passage 9and in which on the under side thereof is formed a longitudinal slot 10,said slot communicating with the passage 9 as clearly shown in Fig. 6 ofthe drawing. Slidably engaged with the passage 9 in the extension 8 ofthe protractor plate is a try square 11 in the longer blade 12 of which,adjacent to the inner edge thereof is formed a longitudinal groove 13adapted to receive a loop 14 formed on the outer end of the extension 8whereby the square is securely held in sliding engagement with theprotractor plate. 12 of the try square when thus engaged with thepassage 9 and slot 10 in the protractor plate is adapted to he slippedback and forth through the slot 2 in the base member 1 and thus adjustedto any desired position as clearly shown in Fig. 1 of the drawings. Inthus arranging the square the position of the same will be indicated bythe scale thereon and the angle at which the same is adjusted will beindicated by the scale on the protractor plate in conjunction with thepointer 15 formed by notching the outer edge of the base member asshown. The try square when thus adjusted is securely fastened bytightening up the clamping bolt 4 which will press the connectingportions of the protractor plate and the sides of the base member intotight engagement with the blade of the square. When not in use thesquare may be swung around to bring the blade 12 in parallel relation tothe base 1 with the inner edge of the blade in engagement with theadjacent portion of the slot 2 in the base member while the rightangular shorter blade 16 of the square is engaged with a groove orrecess 17 formed in one end of the base member as shown in Fig. 2 of thedrawin s.

If desired the square 11 may be disengaged from the extension 8 of thepro- The blade.

tractor plate and removed from the base member 1 and employed in theusual manner.

On one or both sides of the longer blade 12 of the square is preferablyarranged a computing scale or series of scales for indicating thelengths of rafters for various angles or pitches.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described my invention, what I claim is:

1. A framing tool comprising .a base member having formed therein alongitudinally disposed slot and having at one end a transverse recess,a protractor plate pivotally mounted in said base member, an extensionformed on one edge of said protractor plate, a try square having aslidable connection with said extension and adapted to be adjustedtherein and continuously extending within the slot in said base member,means whereby the position of the square is indicated on the protractorCopies of this patent may be obtained for plate, and means tosimultaneously fasten the protractor plate and the try square in theiradjusted positions.

2. A framing tool comprising a base member having formed therein alongitudinal slot and in one end a transverse recess, a protractor platepivotally mounted in said base member, a clamping bolt arranged throughsaid member and plate whereby the latter is fastened in its adjustedpositions, an extension formed on one edge of said plate, said extensionhaving therein a passage and having a slot communicating with saidpassage, a try square having in one of the blades near its inner edge alongitudinal groove, said grooved edge of the blade having a slidingengagement with the passage and slot in the extension of said protractorplate whereby the blade may be adjusted to various operative positionswith respect to the base member and to a folded position in parallelrelation with the base member in which position the inner edge of theshorter blade of the square will be engaged with the transverse recessin the end of said base member.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. V
